Reliability and availability (Part 3: Semiconductor redundancy) Today we gonna talk about N+1 semiconductor redundancy. When is it needed? What are the benefits and drawbacks? The main purpose of redundancy is to increase reliability and availaibility of a system. Therefore, to answer if N+1 semiconductor redundancy is needed, we shall Read more…
Reliability and availability (Part 2: MTBF) Let’s start with the mystery around MTBF (Mean Time Between Failures). You may disagree with me, but please give me a chance and read to the end before you make your mind. Many people believe that the higher MTBF figure the more reliable system Read more…
Reliability and availability (Part 1: Introduction) Reliability and availability are crucial characteristics of drive systems and every downtime negatively impacts the productivity and profitability of a plant. In this series we would like to walk through the topic, provide some (theoretical) background and also a more practical approach. We have Read more…
